hi everyone im new to this forum.
and i have a couple of problems with my 1999 escalade
when i go to lower my windows my car loses power, the radio goes off and so does the A/C. the radio would turn back on if i hit the center console.
does anyone know whats going on?
any help is appreciated. thanks

I would check in the first place the ground connection from battery (and clean battery terminals as well) to body of the truck. Does is starts ok?

well i think its not the battery cuz it starts up just fine.
i heard it was the BCM (body control madule)

Maybe the ground connection to the engine from the battery is ok. One easy test you can do is take some jumper cables, ground negative terminal from battery to a good ground on the body of the truck. Does any other current draw (light on, wipers, horn, fan on, etc) cause the same issues? Did you have any work done on the truck or anything new (electronic) added recently?
